Abstract
Flawless installation of conventional clay cover system in semi-arid areas is almost an impossibility. Cracks and microfractures in clay cover system leading to high seepage and plume migration has been experienced by many landfills in semi-arid areas. A modified cover system developed by the author at Tinker Air Force Base, Oklahoma is designed to overcome the leakage effect by using manufactured clay liners in combination with a thin cushion of clay layer. Another major disadvantage of the conventional clay cover system is the mounding effect of the cover system and the resulting capture and conversion of the contiguous clean and usable land into “hazardous” landfill site. The modified cover system is designed to reduce the mounding effect to a minimum and it does not capture any buffer areas for inclusion in the hazardous landfill site. Hydrologic Evaluation of Landfill Performance (HELP) models showed significant improvement in reducing the percolation for the modified cover system over a conventional one.

Modified Cover System for Hazardous Waste Landfills in Semi-arid Areas
St. Louis, Missouri
Flawless installation of conventional clay cover system in semi-arid areas is almost an impossibility.

A modified cover system developed by the author at Tinker Air Force Base, Oklahoma is designed to overcome the leakage effect by using manufactured clay liners in combination with a thin cushion of clay layer. Another major disadvantage of the conventional clay cover system is the mounding effect of the cover system and the resulting capture and conversion of the contiguous clean and usable land into “hazardous” landfill site. The modified cover system is designed to reduce the mounding effect to a minimum and it does not capture any buffer areas for inclusion in the hazardous landfill site. Hydrologic Evaluation of Landfill Performance (HELP) models showed significant improvement in reducing the percolation for the modified cover system over a conventional one.
